CABINET-FINISHING TOOL.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed February 1, 1909. Serial No. 475,342.

To all whom it may concern.-

Be it known that I, J OHN F. WEBER, residing in West Allis, in thecounty of Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Cabinet-Finishing Tools, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention has for its object to provide a cabinet finishing toolwhich will combine a cabinet scraper of a simple and eflicientconstruction with a sandpaper block to be used in conjunction therewithand also being of a simple and durable construction which will permit ofreadily replacing the sandpaper covering when desired and will firmlyhold the same in place when properly adjusted for use.

With the above and other objects in view the invention consists in thecombined cabinet scraper and sandpaper block herein claimed, its partsand combinations of parts and all equivalents.

Referring to the accompanying drawings in which like characters ofreference inclicate the same parts in the diflerent views; Figure 1 is aplan view of a combined cabinet scraper and sandpaper block of thisinvention; Fig. 2 is a side elevation thereof with the parts in positionfor sand papering; Fig. 3 is a similar view thereof with the parts inposition for scraping; Fig. 4: is a central sectional view thereof; Fig.5 is a detail sectional view of a fragment thereof; Fig. 6 is a bottomview of a modified form of clamping plate for the scraper blade havingguard flanges to regulate the depth of cut of the scraper blade; and,Fig. 7 is an end elevation thereof.

In these drawings 10 indicates a frame, preferably in the form of a castmetal plate with a handle 11 pivotally mounted thereon by havingtrunnions on its forked end fitting between bent over lugs or ears 12 onone face of the frame. The handle 11 may be locked in different angularpositions with relation to the frame by means of set screws 13 threadedthrough the yoked portion thereof and engaging notches provided thereforin a projection 14 which is either formed on the frame or is rivetedthereto as shown.

Sockets 15 are formed on the frame at the ends of an openingtherethrough, which sockets constitute bearings for trunnions 16 at theends of a curved swinging locking member 17 passing through saidopening, there being lugs 18 on the projection 14; bearing on the wallsof the sockets 15 to confine the trunnions therein. The curved lockingmember 17 is adapted to enter an opening in a lug 19 on the top of asandpaper block or plate 20 and a set screw 21 is threaded through aflange 22 of the frame 10 and engages a shoulder on the locking memberto cause said locking member to swing on its trunnions and draw thesandpaper block 20 toward the frame 10. This action serves to clamp theedges of a strip of sandpaper 23 between the flange 22 and the sandpaperblock and also between a corresponding flange 24 at the opposite edge ofthe frame and said sandpaper block, the sandpaper block being providedwith flanges 25 to fit outside of the flanges 22 and 24 to form a moresecure engagement for the edges of the sandpaper. Preferably a padding26, which may be a sheet of rubber or other yielding substance, ismounted on the face of the sandpaper block 20 to constitute a yieldingbacking for the sandpaper and assure a contact of the sandpaper with thework throughout its entire working surface.

On the opposite side of the frame 10 from the sandpaper block and at theedge thereof which is opposite the projection let there is a flange 27with a series of beveled webs 28 forming a seat for a scraper blade 29which is-clamped thereon by means of an angular clamping member 30 withpivot lugs 31 at one edge entering openings provided therefor in theframe 10 to pivotally mount said clamping plate on the frame, therebeing a set screw 32 passing through an opening in the clamping plate 30and threaded in the plate 10 to hold it with pressure against thescraper blade.

When it is desired to provide a gage for limiting the degree of cuttingaction of the scraper blade a modified form of clamping plate issubstituted for the clamping plate 30. This modified form of clampingplate is shown in Figs. 6 and 7 and as applied to the device in Fig. 2and is indicated by the reference numeral 30, it being substantially thesame as the clamping plate 30 with the addition of side runners orguides 33 which ride on the surface of the work and guard the edge ofthe scraper blade so that it cannot dig too deeply into the work.

In operation the tool is first used in the position shown in Fig. 3where the handle is preferably locked to the frame by tightening the setscrews 13 and at such an angle as to give the scraper blade 29 thedesired angle with relation to the work, the scraping operation beingperformed by merely drawing the tool over the work with pressure on thehandle so that the scraper blade 29 scrapes the A surface. When thescraping operation is completed the tool is inverted When it becomesnecessary to replace the strip of sandpaper with another it is onlynecessary to loosen the set screw 21 which will allow the sandpaperblock 20 to back away from the frame 10 so that the edges of v thesandpaper are released from the flanges and it may be easily slipped outof place and another as easily inserted when the set screw 21 is againtightened to drawthe sandpaper block 20 toward the frame and clamp theedges of the sandpaper as before.

' When it is desired to remove the scraper blade 29 to sharpen it or toreplace it with another, it is only necessary to release the set screw32 which permits the clamping plate 30 to swing on its pivotalconnection with the frame, and when the gage is desired the set screw 32is removed so that the clamping plate 30 may be swung back to asuflicient extent to release its hook members 31 from engagement withthe frame and the clamping plate 30 is substituted therefor as shown inFig. 2.

This invention provides in the one tool a simple and efficient cabinetscraper for scraping the surface of the work and a sandpaper block forsmoothing the scraped surface, only requiring the tool to be inverted tochange it from one use to the other.

What I claim as my invention is; 1. In a cabinet finishing tool, aframe, a handle mounted thereon, flanges on the frame, a sandpaper blockprovided with block, a clamping member pivotally mounted-on the frameand adapted to engage the projection of the sandpaper block, and a setscrew threaded on the frame and engaging the clamping member to cause itto swing and draw the sandpaper block toward the frame to clamp theedges of the sandpaper between the flanges.

2. A cabinet finishing tool, comprising a frame, a handle pivotallymounted thereon, a projection on the frame, a set screw on the handleengaging the projection to lock the handle in angular adjustments on theframe, flanges 011 the other side of the frame, a sandpaper block havingflanges fitting with the flanges of the frameto clamp the edges ofsandpaper between them, a projection on the sandpaper block, a clampingmember pivotally mounted on the frame and adapted to engage theprojection of the sandpaper block, and a set screw threaded on the frameand engaging the clamping member to cause it to draw the sandpaper blocktoward the frame.

3. A cabinet finishing tool, comprising a frame, a yoked handlepivotally mounted thereon, a projection on the frame, set screws on thehandle engaging the projection to lock the handle in various angularadjustments on the frame, flanges on the opposite side of the frame, asandpaper block having flanges cooperating with the flanges of the frameto hold the edges of sandpaper between them, an arched projection on thesandpaper block, there being an opening in the frame through which thearched projection of the sandpaper block passes and'sockets at the endsof said opening, a clamping member having trunnions fitting in thesockets and being adapted to engage the arched projection, lugs on theprojection of the frame closing the sockets,

and a set screw threaded on the frame and engaging the clamplng memberto cause it to draw the sandpaper block toward the frame.

' In testimony whereof, I afliX my signa ture, in presence of twowitnesses.
